Breakdown of A9 traffic flow: EIR release

Information request and response under the Environmental Information (Scotland) Regulations 2004

Information requested

You asked –
‘Is it possible to have some info on traffic that use the A9 annually, irrespective of type or class of vehicle’

You clarified on 14 September that you required the number or types of vehicles that currently use, or will use the trunk road A9 in the future.


As the information you have requested is ‘environmental information’ for the purposes of the Environmental Information (Scotland) Regulations 2004 (EIRs), we are required to deal with your request under those Regulations. We are applying the exemption at section 39(2) of the Freedom of Information (Scotland) Act 2002 (FOISA), so that we do not also have to deal with your request under FOISA.

This exemption is subject to the ‘public interest test’. Therefore, taking account of all the circumstances of this case, we have considered if the public interest in disclosing the information outweighs the public interest in applying the exemption. We have found that, on balance, the public interest lies in favour of upholding the exemption, because there is no public interest in dealing with the same request under two different regimes. This is essentially a technical point and has no material effect on the outcome of your request.

Some of the information you have requested is available from with more detail on current and future traffic flow available as part of the design development and environmental statements published for each of the 11 separate sections of the A9 Dualling Programme at Under regulation 6(1)(b) of the EIRs, we do not have to give you information which is already publicly available and easily accessible to you in another form or format.

Please see Annex A to this response which contains traffic figures for the A9 from January 2017 – September 2021. These figures are the annual average daily traffic numbers which include all vehicle types permitted to travel on the route.
